AnandTech Storage Bench - The Destroyer

The Destroyer is an extremely long test replicating the access patterns of very IO-intensive desktop usage. A detailed breakdown can be found in this article. Like real-world usage, the drives do get the occasional break that allows for some background garbage collection and flushing caches, but those idle times are limited to 25ms so that it doesn't take all week to run the test. These AnandTech Storage Bench (ATSB) tests do not involve running the actual applications that generated the workloads, so the scores are relatively insensitive to changes in CPU performance and RAM from our new testbed, but the jump to a newer version of Windows and the newer storage drivers can have an impact.

We quantify performance on this test by reporting the drive's average data throughput, the average latency of the I/O operations, and the total energy used by the drive over the course of the test.

ATSB - The Destroyer (Data Rate)

The overall performance of the Mushkin Source on The Destroyer is a step backwards from other DRAMless SSDs we've tested recently, including the HP S700 that uses an older generation of Micron 3D TLC NAND.

ATSB - The Destroyer (Average Latency)ATSB - The Destroyer (99th Percentile Latency)

The average and 99th percentile latencies from the Mushkin Source during The Destroyer are quite high, though not unprecedented given how other DRAMless SSDs have performed. The average latency from the Mushkin Source is slightly better than the Toshiba TR200, but the 99th percentile latency is in last place among this collection of drives.

ATSB - The Destroyer (Average Read Latency)ATSB - The Destroyer (Average Write Latency)

The three DRAMless drives stand out with substantially higher average read latencies than the mainstream SATA SSDs, and the Mushkin Source is the worst of the three. Average write latencies are very high for the Mushkin Source and the Toshiba TR200, but the HP S700 is only slightly worse off than the slower mainstream drives with DRAM caches.

ATSB - The Destroyer (99th Percentile Read Latency)ATSB - The Destroyer (99th Percentile Write Latency)

The DRAMless drives have much higher 99th percentile write latencies than the mainstream SATA drives, but the Mushkin Source's 233ms is not as bad as the 327ms from the TR200. For 99th percentile read latency, the Mushkin Source is in last place and the other two DRAMless drives have scores that are competitive with many of the mainstream drives.

ATSB - The Destroyer (Power)

The Mushkin Source requires more energy than most SATA drives to complete The Destroyer, but some of the older mainstream drives that also have generally poor performance use even more energy. The other two DRAMless SSDs have average or slightly above average efficiency on this test despite their low performance.
